This is a nightmare! Tadayoshi Kohno, Professor at Department of Computer Science and Engineering, University of Washington, manipulated a STOP sign in a typical “graffiti way”, that it was recognized as 45 mph SPEED limit by typical AI software, such as built into a Tesla S. It’s very likely, that it will become a sport to […]

Last month, my colleagues Frederick Ryckbosch and Samuel Vandamme faced each other for a fun and geeky OpenShift Commons webinar on proactive performance management of Red Hat OpenShift. Samuel came armed with a set of challenging questions and Frederick had CoScale’s container monitoring tool fully loaded to respond. They battled around the different performance considerations […]

This is the second blog in a series of three, in which I expand on some of the points raised in O’Reilly Media’s DevOps for Media & Entertainment report. The first post covered the two essential aspects of DevOps that are often overlooked: communication and empathy. Today, we dive into a more technical topic – monitoring. […]

RxJava is missing a factory to create an infinite stream of natural numbers. Such a stream is useful, e.g. when you want to assign unique sequence numbers to a possibly infinite stream of events by zipping both of them: Flowable<Long> naturalNumbers = //??? Flowable<Event> someInfiniteEventStream = //… Flowable<Pair<Long, Event>> sequenced = Flowable.zip( naturalNumbers, someInfiniteEventStream, Pair::of […]
